can't connect to ender 3 v2 with meatpack plugin installed

[swheettaos]

I'm running octoprint Version 1.5.3 on octopi Version 0.17.0, running on Raspberry Pi 4 Model B Rev 1.2. When I install meatpack 1.5.14 I can't connect to the printer via USB anymore. I have tried disabling the gcode compression and whitespace options. I've also tried with a marlin firmware version from https://marlin.crc.id.au/firmware/Ender%203%20V2%20-%20v4.2.7%20Board%20-%20BLTouch/ .. If I use the previous version without meatpack or the new version with meatpack both have the same problem. If the plugin is installed for meatpack I can't connect to the printer. If I remove the plugin I can connect to the printer just fine. I'm connecting to /ttyUSB0 @ 115200 with no problem. RIght now I removed the plugin and using the EEPROM editor plugin for octoprint I can see the meatpack option is set to true (and was false on the previous version) .. I'll submit this and make sure I clean up the plugin (I had tried installing 1.5.9 earlier and it wasn't working.. I tried again and it installed 1.5.14 but I didn't do a fresh install.. I'll try that.)

[swheettaos]

nope .. with fresh install of the plugin (removal and cleanup) still just can't connect .. it's timing out when trying to connect to the serial port. If I go in and disable the plugin and restart octoprint it then works just fine. What do you need from me to debug?

[swheettaos]

I'm upgrading to python 3 to see if that fixes it.

Marlin builds from marlin.crc.id.au do not have the MEATPACK mode enabled, so the firmware does not have it enabled.

You will need to enable this preprocessor directive yourself and compile the firmware. Unfortunately it is still a nascent feature, and CI/CD servers haven't yet been updated to enable this feature.

Without the feature enabled in the firmware configuration at build time, it will not work and you will not be able to connect.

[swheettaos]

The latest nightly build has it enabled and I can see it in the firmware options set to true. He just posted about it being enabled on on the firmware builds..

• Added support for Meatpack (2020-01-27 onwards)

[scottmudge]

That's good it's been enabled as of the 27th, What does your octoprint.log file look like?

[swheettaos]

looks like the upgrade to python 3 broke the bed visualizer

[scottmudge]

By the log it looks like the Marlin integration of MeatPack is not sending back the appropriate confirmation message to the OctoPrint plugin, so it is not enabling communication.

Another developer integrated MeatPack into Marlin, but I will look at their code to ensure it is working correctly.

[swheettaos]

ok .. disabling plugin for now

[scottmudge]

Okay I found the issue... they need to emit a space character after

SERIAL_ECHOPGM(MeatPack_ProtocolVersion);

inside of

void MeatPack::report_state().

If you want, you can add the following line after line 207 in meatpack.cpp:

SERIAL_ECHOPGM(MeatPack_ProtocolVersion);

after that line, add:

SERIAL_CHAR(' ');

And it should work, after recompiling. I will create a pull request to fix the issue.

[scottmudge]

Okay I created a PR: https://github.com/MarlinFirmware/Marlin/pull/20896

I will update the readme with a notice.

[FunkeCoder23]

I'm still running into this issue, brand new FW build with meatpack enabled, with your fix in report_state. octoprint.log serial.log

[scottmudge]

Strange, it the firmware doesn't look like it's responding to the MP query commands, so the plugin assumes it's not properly connected.

Is that the entirety of the octoprint.log contents? In @swheettaos log, it was at least receiving the protocol version and whitespace removal flags. The issue there was there wasn't a space between "ON" and the protocol version, and the plugin is looking for that space.

But I don't see any query responses in your log. Which to me would indicate that it's not actually enabled in the firmware, for some reason.

To confirm, you definitely have #define MEATPACK uncommented in Configuration_adv.h, and you did a clean rebuild?

[FunkeCoder23]

#define MEATPACK is definitely uncommented. Here's the process I just did: booted new firmware, (re)enable meatpack plugin, reboot pi, here's the totality of the octoprint and serial logs serial.log octoprint.log

[scottmudge]

Still looks like MeatPack isn't responding at all in the firmware. At the very least it should emit a protocol version. Can you attach a .elf file of the firmware you compiled? Should be in the output directory. The hex will be harder to disassemble, but the .elf should be a lot easier.

[FunkeCoder23]

I had to change the extension for github to allow it: firmware.elf.txt

ETA: This is Ender 3 (V1) with BTT_SKR_MINI_V3 board built with _USB firmware

[scottmudge]

Well the binary indicates it's definitely got MP methods linked into the serial parser, but for whatever reason the MP module is not receiving any of the incoming data.

You should be seeing a line like

octoprint.plugins.meatpack - INFO - [Serial]: Config var [NoSpaces] synchronized (=disabled).

soon after the MeatPack module loads and emits its version number to the log.

Can you try adding:

#define MEATPACK_LOOKUP_TABLE

to Configuration_adv.h and recompiling?

[CRCinAU]

I run the site marlin.crc.id.au. I'm just experimenting with this now and came across this - and trying to get the hotfix going.

The custom builder has had the hotfix https://github.com/MarlinFirmware/Marlin/pull/20896 applied, so I've created one via the builder to test with.

The Terminal window logs:

Changing monitoring state from "Offline" to "Opening serial connection"

Send: N0 M110 N0*125
No answer from the printer within the connection timeout, trying another hello

What specifics do you want to know?

[CRCinAU]

Building again with #define MEATPACK_LOOKUP_TABLE enabled, and I can establish two way connectivity with the printer.

I do note that the N0 M110 N0*125 seems to be repeated a couple of times - which seems strange?

The internet tells me list.clear was added in Python 3.3.

[CRCinAU]

AttributeError: 'list' object has no attribute 'clear'

Which python version? I'm running OctoPi 0.18.0 RC1 which is 64 bit - but also Python 3.7...

[scottmudge]

@ellensp Thanks, I'll remove "clear()" for Python 2.7 support (@CRCinAU - I'm guessing 2.7).

[ellensp]

yes Python 2.7.16

[scottmudge]

@ellensp I've pushed a compatibility fix for 2.7 (v1.5.17), can you confirm it works?

And @CRCinAU - the N0 M110 N0*125 line is what I think is OctoPrint's way of "handshaking" with the firmware, so it does it a few times until an expected response is established (which is after MeatPack synchronizes the configuration state, which takes a second). Shouldn't hurt anything so long as it receives a response.

Also, has the build configuration changed for the available firmware builds to reflect #define MEATPACK_LOOKUP_TABLE? For the time being it looks like it might be a requirement for functionality.

[CRCinAU]

Yeah - I've added both right now and rebuilt the 20210127 firmware (which the user will have to rename to a unique filename to flash - or wait until 20210128).

Also, the M84 easter egg just does a whole heap of single tone beeps.... Is that dependent on something else?

[CRCinAU]

With the two defines - I got the following on my normal 20mm calibration cube print:

[ellensp]

I've pushed a compatibility fix for 2.7 (v1.5.17), can you confirm it works?

Yes this now get past this point. but getting errors about to enable MEATPACK_LOOKUP_TABLE and re try

[scottmudge]

If the lookup table is the only functional mode, we may want to make that the default (without a define? or with the define pre-established in the configuration header) in the Marlin implementation.

[ellensp]

with #define MEATPACK_LOOKUP_TABLE seems to be working Comp. TX: 1.744 kB Effective TX: 2.693 kB Comp. Ratio: 0.648 Effective TX Rate: 64 Bytes/sec Packing State: Enabled

[CRCinAU]

If the lookup table is the only functional mode, we may want to make that the default (without a define? or with the define pre-established in the configuration header) in the Marlin implementation.

Pretend I'm an idiot..... I'm not quite sure of the difference between using what I assume is a predefined lookup table for ASCII -> binary packing and not having it set via the MEATPACK_LOOKUP_TABLE... What operational difference is there?

[scottmudge]

I had tested to see if a switch/case statement would perform faster than a lookup table in returning the packed character based on it's 4-bit representation.

However, when I looked at the disassembly in Ghidra, it was byte-for-byte identical. So the compiler seemed to optimize both implementations in the same way.

Unfortunately it looks like the switch/case method may not have been translated exactly correctly to Marlin (or perhaps it just wasn't updated on my end), so it does not work.

I always ended up using the table, as it allowed mutability for changing the library of packed characters, if ever I wanted to add that feature for compressing other types of data beyond 3D printing g-code.

@ellensp - We can probably remove the swith/case approach entirely and make the lookup table the default, and remove the preprocessor switch.

[ellensp]

@scottmudge with MEATPACK_LOOKUP_TABLE it has a static table

  static const uint8_t meatPackLookupTable[16] = {
    '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
    '.', ' ', '\n', 'G', 'X',
    '\0' // Unused. 0b1111 indicates a literal character
  };

If you enable space removal... this is going to cause an issue ie space isn't swapped with E so any encoded E's are going to be decoded as a space aren't they?

[scottmudge]

@ellensp - yes, in my Prusa code the table is mutable and the space character is swapped with an "E" (the replacement character define) when whitespace removal is enabled.

When I disassembled making it a static const and making it a mutable array, the disassembly was identical. There shouldn't be a performance benefit to making it static.

Also, (I don't think it is, but just in case) do not make it PROGMEM, since it is referenced so frequently. Those extra cycles for accessing PROGMEM will add up.

[CRCinAU]

Ok, this is all fixed in the new builds of firmware for 20210127 (or use 20210128 to avoid confusion) and MeatPack plugin v1.5.21 which is now available.

Thanks to @ellensp and @scottmudge for the collaboration over the last several hours to iron out every issue we could find and have something much more stable as a general release.

[scottmudge]

Thanks @CRCinAU!

[swheettaos]

ty everyone.. it's working now!
